Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
What is the Electrical condition of a plasma membrane of a resting neuron?
Polarized
When ions move across a plasma membrane what will happen?
they create a flow of electrical currrent that can disturb the resting membrane potential.
What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
Which is the correct term for the movement of an electrical charge across a membrane?
Potential difference.
Is Photosynthesis is conducted in cell membrane?
No you are wrong. It is happening in the chloroplast membrane.
Why do frogs have a membrane?
They all have membranes in order to stimulate senses
What is a membrane potential?
a voltage or electrical charge across the plasma membrane
What is impulse in the nervous system?
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.
Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
When at rest the axon membrane has an electrical charge of?
When at rest, the axon membrane has a negative electrical charge inside compared to outside. This is known as the resting membrane potential and is typically around -70 millivolts.
What is a sudden electrical charge in a neuron membrane is?
Yes.
What is the function of the contraction vacuole?
It is a membrane bound sac.It removes extra water inside the cell.
At the neuromuscular junction, the muscle contraction initiation event is?
binding of acetylcholine to membrane receptors on the sarcolemma
What events occur in a neuron between the stimulus of a nerve and the stimulation of its target cell?
When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less negative. The potential is conducted along the axon to the axon terminal. At the dendrite it stimulates the release of a chemical transmitter, which diffuses across a synapse. The transmitter binds to receptor sites on the postsynaptic cell membrane to stimulate the generation of another impulse.
What is the Electrical condition of a plasma membrane of a resting neuron?
Polarized
What is the contraction or shrinking of the cell membrane of a plant cell in a hypertonic solution in response to the loss of water by osmosis?
plasmolysis
